Bash history when running several term sessions to same account

[Keith Christian]

How do I make the history from one term session available to another
term session?

I might be in a different term session when I want to run the command
line first typed in a different session.

Both terms are logged into the same account on a Linux Mandrake 8.1
server.  If I type in a length command linein one window, how and when
does it become available in the other?  It's all logged to the same
~/.bash_history file isn't it?

Version is 2.05.1(1)-release.

Thanks!

======Keith
